单点金刚石车削中刀具干涉的产生是由于刀具与工件之间存在着微小的低频振动。它不可避免地影响金刚石车削表面的表面质量。本文提出了一种表面形貌仿真模型，用于预测单刀双掷中刀具干涉对表面形成的影响。它利用在工件的有限数量的等距径向截面处预测的表面粗糙度轮廓来构造金刚石车削表面的表面形貌。该方法克服了现有理论只能检测刀具干涉的局限性。通过实际切削实验对模型进行了评价。实验结果与预测结果吻合较好。
Tool interference has its origin from the small amplitude and low frequency vibration existing between the tool and the workpiece in single-point diamond turning (SPDT). It inevitably affects the surface quality of a diamond turned surface. In this paper, a surface topography simulation model is proposed for the prediction of the effect of tool interference on surface generation in SPDT. It makes use of the surface roughness profiles predicted at a finite number of equally spaced radial sections of a workpiece to construct the surface topography of a diamond turned surface. The approach overcomes the limitation of the existing theories that can check only for the existence of tool interference. The model was evaluated through practical cutting experiments. Experimental results were found to agree well with the predicted results.
